It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the one element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1 to 3, the present embodiment discloses an abrasive belt 5 mechanism for a polishing machine, which includes a horizontally disposed working plate 1, the working plate 1 is connected to a frame 100 of the polishing machine through a vertical bracket on one side, and the working plate 1 mainly plays a role of carrying components of the abrasive belt 5 mechanism.

The working plate 1 is provided with a driving wheel 2, a driven wheel 3 and a tension wheel 4 which are respectively used as three support inflection point structures and support an annular abrasive belt 5 on the outer side in a tensioning mode, and the abrasive belt 5 forms a grinding surface in the area between the driven wheel 3 and the tension wheel 4, so that a workpiece positioned at the position can be ground, and the effect of polishing the workpiece is achieved.

Further, the driving wheel 2 is in transmission connection with a driving device arranged at the bottom of the driving wheel, the driving device adopts a motor, and specifically, the driving wheel 2 is directly connected with the motor and can provide driving force for the rotation of the abrasive belt 5.

And a driven wheel 3 is arranged on one side of the driving wheel 2 on the working plate 1, and the driven wheel 3 is connected with the working plate 1 through a rotating shaft and a bearing.
